“…Recently, SOD in RGB-T image [11], light field image [12], [13], [14], high-resolution image [15], [16], optical remote sensing image [17], [18], [19] and 360 • omnidirectional image [20], [21] have been gradually researched. SOD can benefit many image and video processing tasks, such as image segmentation [22], [23], tracking [24], [25], [26], retrieval [27], compression [28], cropping [29], [30], retargeting [31], quality assessment [32] and activity prediction [33].…”
